Appearing Thursday for the last time on the retiring late-night legend’s show, Clooney sat down and, when Letterman asked about Clooney’s life, the “Tomorrowland” star said he didn’t want to talk about that, and asked to see Letterman’s arm. He then handcuffed Letterman onto his own arm.

“Now, George, is this something left over from the bachelor days?” Letterman asked.

Clooney joked that Letterman was the only man he watched while in his underwear before getting serious.

“Here’s the thing,” Clooney said. “What you’ve meant to us with so many of the laughs, walking us through times that we didn’t know what to do, like 9/11 when we weren’t sure when we could laugh again. You belong to us through the ages.”

The stars have turned out the past couple weeks to pay tribute to Letterman, who is leaving after more than three decades on television. Julia Roberts gave him a big kiss. Tina Fey stripped down for him. Adam Sandler wrote him a song.

I can’t wait to see what Bill Murray does on Letterman’s last show, which airs May 20. Stephen Colbert takes over “The Late Show” in the fall.

In a friend's dining room in central Los Angeles, 27 hours before she will announce she's running for president of the United States, I ask self-help author and motivational speaker Marianne Williamson to perform a miracle. Until a few weeks ago, I didn't know Williamson was planning to join the Democratic presidential primary class of 2020.
